FXM2IC102
Dual Supply 2-Bit I2C Interface Voltage Translator with
Configurable Voltage Supplies and Signal Levels and
Auto Direction Sensing
Features
■ Bi-directional interface between any two levels from
1.65V to 5.5V
■ Buffer isolates capacitance and allows 400pF on each
port
■ Open-drain inputs/outputs
■ Accommodates Standard-mode and Fast-mode
I2C-bus devices
■ Fully configurable: Inputs and outputs track VCC level
■ Non-preferential power-up; either VCC may be
powered-up first
■ Outputs remain in 3-state until active VCC level is
reached
■ Outputs switch to 3-state if either VCC is at GND
■ Power off high impedance
■ Active high output enable referenced to VCCA voltage
■ 5V tolerant output enable
■ Packaged in 8-terminal leadless MicroPak
(1.6mm x 1.6mm)
■ Direction control not needed
■ ESD protection exceeds:
– 8kV HBM ESD
(per JESD22-A114 & Mil Std 883e 3015.7)
– 15kV HBM I/O to GND ESD
(per JESD22-A114 & Mil Std 883e 3015.7)
General Description
The FXM2IC102 is a configurable dual-voltage-supply
translator designed for bi-directional voltage translation
over a wide range of input and output voltages levels.
The FXM2IC102 is intended for use as a voltage trans-
lator in applications using the I2C bus interface. Input
and output voltage levels are compatible with I2C device
specification voltage levels.
The device is designed so that the A port tracks the
VCCA level, and the B port tracks the VCCB level. This
allows for bi-directional voltage translation over the
voltage ranges: 1.8V, 2.5V, 3.3V, 5.0V.
The device remains in 3-state until both VCCs reach
active levels allowing either VCC to be powered-up first.
Internal power down control circuits place the device in
3-state if either VCC is removed.
The two ports of the device have auto-direction sense
capability. Either port may sense an input signal and
transfer it as an output signal to the other port.
